Louisville, Ky., assiguors to Double Envelope Corporation, Roanoke, Va.,a corporation of Virginia Filed May 6, 1968, Ser. No. 726,726 Int. Cl.B65d 27/08 U.S. Cl. 229-72 1 Claim ABSTRACT 0F THE DISCLOSURE Anenvelope designed to carry negatives in a back pocket and prints in afront pocket, the back pocket being inexpensively provided by a paperpatch tacked to the interior of the enveloe by two spots of adhesive atthe bottom of the envelope, one at each end of the patch, the depth ofthe back pocket at its center being the full depth of the envelopebetween the two spots of adhesive so that the negatives can slip to thebottom of the envelope between the two spots of adhesive and, thenegatives are held by the spots of adhesive in a position generallycentrally of the envelope length so as to be better protected fromdamage in handling the envelope.

Envelopes are known in which pockets are provided, usually by providingextra long end or bottom tabs to form deep overlaps leaving pocket spacebetween two or more of the tabs internally of the envelope. Suchenvelopes are wasteful of paper and are diflicult to make as theexcessive length of the tabs causes shutdown of the envelope machinewhen a tab does not fold properly.

While pockets have been provided in envelopes by adhering a piece ofpaper by a U-shaped line of adhesive in order to position a businesscard, for instance, so that it can be read through a window in theenvelope, it has not been possible to provide a pocket of the full depthof the envelope.

It is an object of the present invention, therefore, to provide anenvelope with a back pocket of the full depth of the envelope withoutusing unnecessary paper and without requiring the envelope blank to bedifficult to fold in the envelope machine.

Other and further objects and advantages will appear from the followingspecification taken with the accompanying drawings in which the severalreference characters refer to similar parts in the several views and inwhich:

3,482,764 Patented Dec. 9, 1969 ice FIGURE l is a perspective view ofthe envelope of the present invention;

FIGURE 2 is a perspective View of the envelope blank with the pocketforming patch in place; and

FIGURE 3 is a section on line 3-3 of FIGURE 2.

It will be seen that the envelope is made of a blank having a back panel1, a front panel 2 that is secured by a fold line to back panel 1 andoverlies and is adhesively secured to end tabs 3 and 4. A closure 5 issecured by a fold line to the top of the back panel 1.

From FIGURE 2 it will be seen that the paper patch 6 is adhered to theback panel 1 only at two points 7 and 8hbefore the blank is fed into theenvelope folding mac me.

The quality of the paper patch may be selected according to the specificuse to which the envelope is to be put. For use with photographicnegatives the patch 6 should be of a paper that will not scratch oradhere to photographie negatives and, if the envelope is to be mailed,may be of relatively stiff material to reduce likelihood of inadvertentfolding of the envelope and contents in the mails.

The width of the paper patch is desirably great enough to besubstantially coextensive of the enclosed negatives when they are inposition in the envelope with their edges at the bottom edge of the backpanel, and between the two adhesive spots.

Having thus described the invention, what is claimed is:

1. An envelope comprising a back panel having a bottom edge, end edges,and a top edge, to which edges are attached a front flap folded inwardlyfrom said bottom edge, two end flaps folded inwardly from said endedges, and a closure flap secured by a fold line to the said top edge ofsaid back panel, and a paper patch of a length c-orresponding to theinterior length of the envelope said patch being secured solely by twosmall adhesive spo-ts interiorly of the envelope, said spots securingSaid patch to said back panel only at its extremities adjacent saidbottom edge.
